The oral solid tablet has good drug release characteristics, features easy administration, quick and high-efficient release, no particular requirements on equipment, and a simple formulation preparation process, can ensure formulation stability and facilitate transportation and storage, and is suitable for large-scale production.

TECHNICAL FIELD

The present invention relates to an solid tablet for oral administration containing a Bruton's Tyrosine Kinase (BTK) inhibitor, in particular (S)-7-[4-(1-acryloylpiperidine)]-2-(4-phenoxyphenyl)-4,5,6,7-tetrahydropyrazolo[1,5-a]pyrimidine-3-carboxamide and a preparation method thereof.

BACKGROUND ART

International application WO 2014173289 A disclosed a novel Bruton's Tyrosine Kinase (BTK), more particularly (S)-7-[4-(1-acryloylpiperidine)]-2-(4-phenoxyphenyl)-4,5,6,7-tetrahydropyrazolo[1,5-a] pyrimidine-3-carboxamide (with a generic name of Zanubrutinib), which has a chemical structure as follows:

Zanubrutinib belongs to the second-generation BTK inhibitor, which irreversibly inactivates the tyrosine kinase by covalently binding with the enzyme. It is used as a single agent or in combination with other drugs for the treatment of B lymphocyte tumors, including chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), mantle cell lymphoma (MCL), Waldenstrom's macroglobulinemia (WM), follicular lymphoma (FL), non-germinal center subtype diffuse large B-cell lymphoma (non-GCB DLBCL), etc.

The active pharmaceutical ingredient of Zanubrutinib is slightly hygroscopic. DSC results show that the compound has a distinct endothermic peak when it melts, and has an initial temperature and a peak temperature of 139° C. and 144° C., respectively. The melting point of the active pharmaceutical ingredient is 145° C., which is lower than the ideal melting point of 150° C. for tablet development, and the material is relatively viscous, which poses a huge challenge to the development and large-scale industrial production of Zanubrutinib tablets. In addition, the Zanubrutinib has a pH-dependent solubility and belongs to class II (low solubility, and high permeability) drug of the biopharmaceutical classification system. Therefore, there is an urgent need to develop a Zanubrutinib tablet in which the active ingredient can dissolve quickly from the preparation, so as to maintain the rapid release of the drug in the whole intestine with good bioavailability.

SUMMARY OF THE INVENTION

In order to overcome the deficiencies in the physicochemical properties of Zanubrutinib active pharmaceutical ingredient (API), such as high viscosity, poor fluidity, and poor solubility, etc., and to ensure good dissolution of the drug, the present invention provides an solid tablet for oral administration containing Bruton's Tyrosine Kinase inhibitor of Zanubrutinib and a preparation method thereof. The inventors of the present invention unexpectedly discovered that a certain amount of colloidal silica as a glidant and other excipients have a significant contribution to improve the sticking of the drug and ensure a good dissolution rate of the drug. The solid tablet for oral administration of Zanubrutinib of the present invention can be released relatively quickly in a medium containing sodium lauryl sulfate at pH 1.2 (HCl), for example, the dissolution rate can reach more than 80% within 30 to 60 min at some prescription excipient ratios; preferably, the dissolution rate of Zanubrutinib can reach more than 95% within 30 min at some prescription excipient ratios. In addition, the solid tablet for oral administration of Zanubrutinib of the present invention has no special requirements for production equipment, has a simple preparation process, a stable product, and low production costs.
